United States District Judge Mark Pittman formally rejected xAI’s attempt to shield Elon Musk’s Tesla and SpaceX communications from discovery on Tuesday. The judicial order compels Musk to hand over his business email accounts, texts, and Xchat records from across his aerospace and automotive companies to be reviewed in the ongoing lawsuit against Apple and OpenAI, according to 9to5Mac.
The legal battle originates from August 2025, when Musk’s xAI sued Apple and OpenAI over allegations of an illegal monopoly. Musk claimed Apple’s deep iOS integration of ChatGPT deliberately marginalized competing artificial intelligence models like xAI’s Grok. By burying Grok in the App Store rankings, the lawsuit argued xAI was deprived of the critical prompt volume generative AI algorithms require to train and improve.
The discovery phase of this lawsuit has moved sluggishly through the federal courts. While Apple SVP of Software Engineering Craig Federighi was successfully brought in as a document custodian in May 2026, a subsequent request to compel Apple CEO Tim Cook to participate was denied, reported by AppleInsider. Judge Pittman determined that isolating discovery to just xAI was invalid because evidence showed Musk actively utilized his Tesla and SpaceX accounts to conduct business for both X and xAI.
The court granted OpenAI’s specific request to compel the cross-company communications on June 2, while simultaneously rejecting xAI’s request to force Apple to hand over internal documents detailing its own AI operations.
What the Court Ruling Means for the Musk Corporate Empire
This domestic defeat compounds a string of recent international legal setbacks for Musk’s legal team. Courts in Singapore and the Korean Supreme Court formally rejected xAI’s sweeping global discovery requests seeking internal documents from regional super-apps like Kakao earlier in the week, according to MacTech.
The Tuesday ruling establishes a major legal precedent for Musk’s interconnected business operations. Because the billionaire frequently mixes his management efforts, the courts have signaled that isolating liability or discovery to a single entity like xAI is invalid if executive communications bleed into his other organizations.
The decision exposes Tesla and SpaceX internal communications to the scrutiny of Apple and OpenAI attorneys during the discovery process. Legal teams will now sift through the aerospace and automotive archives to locate conversations regarding X and xAI.
